I started with pain in lower back and that went away and I now have weakness to the point that I'm not really walking much. Now I have pain behind my knees, and even my feet burn. I feel like I'm nuts because I feel no pain when sitting quietly or lying still. What could the problem be?
Low back pain, weakness, burning pain... nope, you are not nuts. You have a nerve problem and should be seen by a doctor as soon as possible to see why. Delay in proper treatment could result in permanent nerve damage and/or progression of the problem.
If you lose continence of your bowel or bladder, please go to the emergency room.
This type of problem is frequently better when sitting or lying still... so no, you are not nuts. You are nuts if you do not get proper treatment.
